目的 分析2014～2017年南山区居民伤害死亡流行特征及疾病负担,探讨伤害原因。方法 利用南山区2014～2017年死因登记资料及人口资料,分析伤害死亡率、构成比、潜在减寿年数等指标。结果 2014～2017年南山区居民因伤害死亡247人,死亡率为7.44/10万,标化死亡率为11.65/10万,男女死亡率分别为8.99/10万和5.67/10万,男女伤害死亡率差异有统计学意义(χ²=12.258,P<0.001)。主要伤害中位居前三位的依次为自杀、意外跌落和交通事故。不同年龄人群伤害死因有所不同。伤害造成的PYLL为6 358人年,APYLL为25.74人年。自杀造成的PYLL最大,为 2 768人年。结论 伤害已成为南山区居民死亡的主要原因之一,其中自杀对居民疾病负担的影响最大。应根据不同人群的主要伤害原因制定有效防控措施,以降低居民伤害死亡率。

Objective To analyze the epidemic characteristics of injuries and its influence on disease burden among residents in Nanshan district of Shenzhen city from 2014 to 2017, and explore the cause of injury. Method We analyzed the data of population and annual registered death causes in Nanshan district during the period from 2014 to 2017 statistically, calculate the mortality rate, proportion and potential years of life lost (PYLL) due to injury. Results A total of 247 people died from injuries in Nanshan district from 2014 to 2017. The mortality rate and standardized mortality of injury were 7.44/10⁵ and 11.65/10⁵ respectively. The mortality rate of male was significantly higher than that of female (8.99/10⁵ vs 5.67/10⁵, P<0.001). The top three causes of death of injuries were suicide, traffic accident, and accidental fall. The first cause of death of injury from 0 to 4 years old was accidental suffocation, from 5 to 64 years old was suicide, over 65 years old was accidental fall. The PYLL and APYLL of injury were 6358 years and 25.74 years respectively. The PYLL in suicide was the most of all injuries, which was 2768 years. Conclusions Injury has been one of the important death causes in Nanshan district. Suicide had the greatest impact on the disease burden. Effective prevention and control measures should be formulated according to the main causes of injuries among different groups of people to reduce the mortality rate of injuries among residents.
